Worried About Fungus In Your Lawn?
Every lawn gets brown spots here and there; some more visible than others… …but what causes them? Could it be lawn fungus or disease and will it kill your grass? Here are a few simple tips regarding lawn fungus and diseases that can creep into your turf during the later spring and summer.
Frequent rains and humidity coupled with higher temperatures allow for a perfect storm of fungal problems. This is especially true during the months of April, May and June. During these months, your turf is under constant fungal pressure.
Common lawn fungus problems across most of the country are rust disease, red thread, summer patch, and dollar spot. The good new is, however, none of these will do major damage to your turf if you are willing to do a little work and change some of your habits, as well as allow your lawn care company to assist you.
We can’t control the weather, but we can make adjustments in spite of it. The primary cultural practices that homeowners should be aware of are watering and mowing. Mow tall and catch clippings during humid conditions, and always water your lawn deeply, consistently and never at night.
There are also a number of granular fungicides available at your local home and garden center. These will work very well if applied before any sign or fungus or disease occurs. I always recommend homeowners apply fungicides in May and again in late June if warranted. Of course, you should always follow the directions on the product you are applying. If you can’t get to it, hire a lawn pro to do it for you.
Another important consideration is soil composition; specifically in regards to available nitrogen. Nitrogen in the soil will allow grass to grow quickly, thus recovering faster from disease pressure. Your lawn pro can help adjust fertilizer rates for you or apply the correct amounts when diseases are present in the turf.
Lastly and most importantly is the thatch layer in the turf. Thatch is that layer of organic matter that floats just above the soil line in the lawn.
All lawns must have some thatch. When in the correct balance, the thatch layer provides protection for the turf roots and prevents soil erosion. However, when this layer becomes thicker than one-half-inch, it will work against you and harbor fungus. If this is the case, you need to get out and aerate your lawn now and again a few months later to help break it down.
Aerating the lawn is a process whereby holes are punched into the thatch layer and down into the soil using a large machine. You can hire a lawn care company to aerate for you, or rent the machine yourself for around $40 per day. The best times to aerate are spring and fall, but you can do it anytime or both. One last tip: never power rake your turf. Power raking will remove 100% of the thatch layer and cause you bigger problems in the future.
Whatever you do, dont panic if you see a few brown spots popping up in your lawn. Turf grass is very forgiving and tends to recover from most anything. Lawn care doesnt have to be stressful. Just be sure to do your part with the mowing and watering and your lawn will stand up straight tall and green all year long.
